Laravel 5: Removing Elements From an Array With forget
The forget helper method in Laravel's Arr class allows you to easily remove items from an array using dot notation for specifying keys. This method modifies the original array directly, so there's no need to reassign the modified array to a new variable. You can also use the array_forget function as a shortcut to calling Arr::forget.
Laravel 5: Representing Multi-Dimensional Arrays in Dot Notation With dot
The dot helper method in Laravel allows you to convert a multi-dimensional array into an associative array where the keys are created from the nested keys separated by a dot. You can also prepend a value to all the newly generated keys by using the $prepend argument. Additionally, there is a global array_dot helper function available as a shortcut to calling Arr::dot in Laravel.
Laravel 5: Retrieving, and Removing an Element From an Array With pull
The pull helper method in Laravel is used to retrieve and remove a value from an array. It can be used with a default value if the desired key does not exist. This method directly modifies the original array. An example use case is removing a specific day from an array of weekdays in PHP. The pull method can be accessed through the Arr class in Laravel, or through the global array_pull helper function.
Laravel 5: Retrieving Elements from an Array With get
The get helper method allows developers to quickly retrieve items from an array using dot notation, without having to use PHP's array syntax. The method also supports a default value, which will be returned if the specified key is not found in the array. An alternative to using the get method is to use PHP's array access syntax and the isset function, but the dot notation code is shorter and easier to read. Additionally, there is a global array_get helper function available as a shortcut to calling Arr::get.
Laravel 5: Retrieving Nested Array Values With pluck
The pluck helper method is used to retrieve specific values from an array. It can be used on arrays of objects or arrays of arrays. You can also use dot notation to retrieve values from nested arrays or objects. Additionally, there is a global array_pluck function available as a shortcut to Arr::pluck.
Laravel 5: Retrieving Random Elements from an Array With random
The random method in PHP's Illuminate\Support\Arr class allows you to retrieve random items from an input array. You can specify the number of random items to be returned, and if not specified, it will return one random item. Be cautious when specifying a number greater than the array's length, as it will throw an exception. Note that the random method is not suitable for cryptographic purposes since it relies on PHP's array_rand function. There is also a global helper function, array_random, that serves as a shortcut to calling the Arr::random method.
Laravel 5: Sorting Arrays With sort
The sort helper method allows you to sort an array based on some condition returned by a callback function. It iterates over the values in the array and uses the value returned by the callback to determine the sort order. You can also use the array_sort function as a shortcut to calling Arr::sort. Keep in mind that the array_sort function internally creates a new Collection object and should not be used in a certain way to avoid unnecessary object creation.
Laravel 5: Splitting an Array Into It's Keys and Values with divide
The divide helper method in Laravel separates an array into two new arrays: one containing all the keys and the other containing all the values. This can be useful when you need to work with the keys and values separately. You can use the divide method by calling Arr::divide and passing in the array you want to divide. Additionally, Laravel provides a global array_divide helper function that is a shortcut to calling Arr::divide.
Laravel 5: String Translation Public API
The "Illuminate\Translation\Translator" class in Laravel is responsible for handling translation services. It can be used to retrieve translation lines, process replacements, and specify a locale. The get method retrieves the translation line for a given key, with the option to pass in replacements. The getFromJson method is similar, but allows retrieval from JSON-based language files.
Laravel 5: Encoding HTML With the "e" Helper Function
The e function is a convenient PHP wrapper for the htmlentities function, allowing you to sanitize user input when displaying it on a webpage. It encodes HTML special characters, preventing malicious users from injecting JavaScript or other code into your website. The function also handles Htmlable values differently and does not encode the HTML characters within their toHtml() return value. By using the e function, you can ensure that your webpage is safe and protected from cross-site scripting (XSS) attacks.
